摘要随着重要军事基地等战备工事的深层次化和各种战车装甲防护的加强，军事战略指标对钻地弹和动能穿甲弹的侵彻要求也随之不断提高，因为这一类弹药在实际攻击使用过程中将遇到各种不同的环境条件，有的相当恶劣、复杂，这就要求弹药在高加速度过载环境下具有很高的可靠性。63836

弹药的可靠性主要取决于其中火工品的可靠性，所以提高火工品在高加速度过载环境下的可靠性就成了近年来军事科学的一个热点研究方向。本文以冲击片雷管为研究对象，利用空气炮对其进行高过载试验，并进行了撞击过程的数值模拟，探讨了不同材料下冲击片雷管的抗过载能力。

冲击片雷管作为一种半导体桥雷管，它结合了爆炸箔冲击片起爆技术，并在近年来受到大量关注和发展，本文简要介绍了冲击片雷管的作用原理和结构组成，以及在ANSYS/LS-DYNA软件中的模拟方法。

并且文章也介绍了目前国内外对火工品高过载的实验研究方法，主要有马歇特锤击试验方法、落球碰撞试验方法、冲击摆试验方法、Hopkinson杆应力波加载试验技术、空气炮加载碰撞、等来模拟冲击中的高过载环境。

最后利用有限元数值模拟软件ANSYS/LS-DYNA模拟了冲击片雷管的空气炮过载试验，得到了不同材料下和不同速度下的过载数据。

Abstract With such an important military base of the deep combat readiness fortifications and a variety of enhanced armor protection tanks， military strategic targets on Earth Penetrator and kinetic energy penetrators penetration requirements also will continue to improve， because this type of ammunition in the actual attack use process will encounter a variety of different environmental conditions， some quite harsh and complicated， which requires ammunition at high acceleration overload conditions with high reliability.

Which mainly depends on the reliability of munitions Pyrotechnics reliability is improved EED at high accelerations reliability overload environment has become a hot topic in recent years， military science research. In this paper， slapper detonators for the study， the use of air guns its high overload test， and had hit Numerical simulation， the effect of different materials under slapper detonators anti-overload.

Slapper detonator as a semiconductor bridge detonator， which combines the exploding foil slapper initiation technology， and in recent years by a lot of attention and development， the paper briefly describes the role slapper detonators principles and structures， as well as in ansys/ls-dyna software simulation methods.

And the article also describes the current home and abroad Pyrotechnics high overload experimental research methods， including Machete hammering test methods， falling ball impact test methods， impact pendulum test methods， Hopkinson bar stress wave loading test technology， air gun loaded ， etc. to simulate the impact of high overload environment.

Finally， the finite element numerical simulation software ansys / ls-dyna slapper detonators simulated air cannon overload test， obtained under the different materials and different speeds of data overload.

Key Word: Slapper detonator; high overload; air gun; ansys / ls-dyna; numerical simulation
